Abstract
In one aspect, a method of obtaining projection data of an object from a plurality of view angles with respect to the object is provided. The method comprises acts of providing radiation, at each of the plurality of view angles, to an exposure area in which the object is positioned, controlling a radiation energy of the radiation provided at each of the plurality of view angles such that the respective radiation energy is different for at least two of the plurality of view angles, and detecting at least some of the radiation passing through the exposure area at each of the plurality of view angles to obtain the projection data.
